You could do that; wrap it in plastic wrap or wax paper and allow to chill in the refrigerator. You could probably roll it in something tasty and decorative like chopped pistachios prior to wrapping. Or try shredded coconut (might toast a little, try baking a sample first.) You could cut the roll in halves or thirds and freeze some for later if you don't want to bake it all at once. Use a sharp knife to slice.
